摘要
We propose a side-polished fiber sensor coated with a metal/oxide surface-plasmon-resonance sensing film, in which an AZO layer is added between a metal film and the side-polished surface of the fiber core to improve the device’s detection performance. The metal/AZO bi-layer film is used as the active sensing member of the device. Such a device is then applied to the concentration measurement of CH3COONa solutions. The results indicate that the additional AZO layer in the active sensing member may give rise to lower detection limits and greater sensitivity. © 2015, National Institute of Optoelectronics.
